LM1875T/LB02

The LM1875T/LB02 is a high power audio amplifier that is ideally suited for use as a booster in car audio systems. It is a single-channel amplifier with both mono and dual mono outputs, allowing it to be used as a single-channel amplifier or as a distributed amplifier for stereo applications. The amplifier has a wide range of features that make it highly versatile for use in a variety of applications.

The LM1875T/LB02 amplifier has a power output of 20 watts per channel. This power can be adjusted via the Onboard tone control which offers bass and treble tactile control and balance trim. The amplifier also features a built-in, low-noise input stage, along with a switchable low-pass filter with a cutoff frequency of 5kHz. A built-in limiter is also included, which helps to protect the speakers from potential distortion and clipping.

The amplifier has high gain, low output offset, and low distortion. The frequency response is flat, making it ideal for use with digital music sources. The power supply circuitry is designed to minimize noise and distortion, while the output stage has high current capability and protection against short-circuits and over-voltage conditions.

The LM1875T/LB02 amplifier is a single-channel audio amplifier, but it can be used as a dual-channel amplifier for stereo applications. It has a mono output for one amplifier channel, and a dual-mono output for the second channel. This allows the user to have multiple speakers connected to each amplifier channel. The output is adjustable via an Onboard volume control.

The working principle of the LM1875T/LB02 audio amplifier is based on the principles of electrical amplifiers. It takes an input signal, amplifies it, and outputs an increased level of the original signal. The amplifiers used in this device employ a transimpedance gain stage, which amplifies the voltage of the input signal, and a power stage, which provides the necessary power to drive the speaker/s. The amplifier’s gain is adjustable via the onboard tone control, which can also be used to adjust the frequency response and achieve a more balanced sound.

The LM1875T/LB02 amplifier is a versatile and powerful device, suitable for a variety of applications. It is ideally suited for use as a booster in car audio systems, as well as for boosting power output for professional audio systems. It also has the potential to be used as a single-channel amplifier or a distributed amplifier for stereo applications. With its wide range of features and adjustable tone control, it offers many advantages to audio engineers and sound professionals.
